Excel 2007 : Sumifs help

Hello all who can help!

I have a problem I have been struggling with for days. I have attached an excel file similar to what I am working with.

There are two worksheets: Summary and Data. On the summary worksheet, in cell B3, I am trying to count the # of Non Tech calls for Monday, January 02, 2012 from the Data worksheet.

I have tried to use a sumifs formula but it doesn't work because of the date headings on the data worksheet. I have no experience with offset formulas so I don't know where to begin.

Does this make sense and if so can anyone help?

Thanks in advance!
